Symmetrical bis‐substituted anthraquinones were successfully prepared and demonstrated potent cytotoxicity against the growth of suspended murine and human tumors, i.e. rat glioma C6 cells and human hepatomaG2 cells.We report here a convenient synthetic pathway that leads to symmetrically substituted 1, 5‐bisacyloxyanthraquinone derivatives. Acylation of the hydroxyl group of 1, 5‐dihydroxyanthraquinone
对称双取代蒽醌类化合物已成功制备,并证明对悬浮鼠和人肿瘤(即大鼠神经胶质瘤 C6 细胞和人肝细胞瘤 G2 细胞)的生长具有有效的细胞毒性。我们在此报告了一种方便的合成途径,可生成对称取代的 1, 5-双酰氧基蒽醌衍生物. 在吡啶或氢化钠的存在下,1,5-二羟基蒽醌的羟基分别与适当的酰氯酰化,提供了这种结构类型的蒽醌。双(丁酰氧基)类似物 2b、双(2-氯苯甲酰)类似物 2f 和双苯基丙酰氧基类似物 2n 在抑制培养中人 hep G2 细胞生长方面表现出有效的细胞毒性,如使用 XTT 比色法测定的,而它们的抗增殖活性显着增强,可与抗癌剂米托蒽醌相媲美。此外,还测定了化合物在模型膜中抑制脂质过氧化的氧化还原特性。化合物2n还表现出比抗坏血酸、(+)-α-生育酚和炭疽菌素更强的抗氧化活性。已经对这些对称蒽醌进行了生物学评价和 SAR 研究,并对结果进行了讨论。

mitoxantrone. Since the telomerase enzyme is a novel target for potential anticancer therapy and stem cell expansion, we explore the biological effects of these compounds by evaluating their effects on telomerase activity and telomerase expression. Telomerase is required for telomere maintenance and is active in most human cancers and in germinal cells but not in most of the normal human somatic tissues.
